Why convert PLY to GLB?
Showcase 3D scans on the web
PLY scans from RealityCapture, Metashape, or LiDAR can be displayed in interactive web viewers by converting to GLB.
AR and WebXR deployment
Apple Quick Look, Google Scene Viewer, and WebXR all expect GLB. Convert PLY scans before pushing them into AR experiences.
Game engine import
Unity and Unreal accept GLB natively. PLY imports as plain geometry with no materials — GLB lets you add them later.
Tips for PLY → GLB
PLY vertex colors are preserved
If your PLY has per-vertex colors, Fast3D bakes them into a texture during conversion. The GLB renders colored in any viewer.
PLY has no materials
PLY does not support PBR materials. The converted GLB uses a default material — add your own in Blender after conversion if needed.
Decimate dense scan meshes
PLY scans can have 5M+ triangles. Decimate in MeshLab or Blender before converting to keep the GLB size manageable.
Binary PLY converts faster
Binary PLY is roughly 4x smaller than ASCII PLY and parses much faster. Use binary when exporting from scanning tools.
Common issues when converting PLY to GLB
Colors look blocky in GLB
Fix
PLY vertex colors are limited by mesh density. Sparse scan meshes produce blocky baked textures. Run the GLB through gltfpack or increase mesh density before conversion.
GLB file is huge
Fix
PLY scans typically have very dense meshes. Decimate in MeshLab (Quadratic Edge Collapse) or Blender (Decimate modifier) before converting. For web delivery, apply Draco compression to the GLB.
Model appears uncolored
Fix
The PLY file has no vertex colors. Fast3D cannot invent them. Open the PLY in MeshLab, compute per-vertex colors from the scan's normals or imported texture, then re-convert.
